Xcitation, you ask “Near the end the PF confides he has been nose up max all the way! Like it is the normal thing to do and he tried his best to pull out of a dive or something. Why is it that . . . ?”
PF’s references to “crazy speed” and his persistent holding nose up suggested to some that he confused mach buffet with pre- stall buffet, and high noise with high speed rather than high AoA, which kept him thinking all the way down that he had an overspeed problem. What do you think?
